Question

Can I switch a boolean with one statement as effectively as with an if/then/else ?

Found this in another piece of code that is going into my app…

    private void whatever()
    {
        ////
        //// a bunch of stuff
        ////

        if (SomeBooleanValue)
        {
            SomeBooleanValue= false;
        }
        else
        {
            SomeBooleanValue = true;
        }
    }

Out of curiosity, I tried this…

    private void whatever_whatever()
    {
        //// 
        //// the same stuff
        //// 

        SomeBooleanValue = !SomeBooleanValue;
    }

…and walked through it in debug, and it appears that I get the same result.

Is there a good reason to use the if/then/else instead of the single line way ?

Answer 1

The 1-line way is perfectly fine, and the only reason why you’d use the if/ else structure is if you were doing other things aside from just toggling the boolean.
